hi guys

i cant seem to work out how to use the autobracketing on my 60D
i just want to be about to take the 3 shots and different exposures automatically. i used to be able to do this on my 450D
and when i try to do it the same way as i did with the 450d i can only get the 60D to shoot one image and not 3.

im hoping that someone on here can shed some light on this for me
